Application iled August 8, 1918.

To all wwm t may concern:

Be it known that I, OLIVER E. CLEVENGER, a citizen of the United States of America, residing at Kingsdown, in the county of Ford and State of Kansas, have invented new and useful Improvements in Stack- Molds, of which the following is a specifica tion.

The invention seeks the provision of a device built in sections which may be assembled to form a closure in which stacks or ricks of hay and grain may be molded.

A further object of the invention resides in the particular formation of the sections comprising the device so that hay or grain stacked therein may not be caught on the sides of the section. This arrangement provides for the formation of a compact stack.

Further objects of the invention appear hereinafter as it is set forth in detail.

To the exact construction in which it is shown and described, the invention is not to be restricted. The right is reserved to make such changes or alterations as the actual reduction to practice may suggest, in so far as such changes or alterations are compatible with the spirit of the annexed claim.

In the accompanying drawings:

Figure 1 is a view in side elevation of the improved mold.

Fig'. 2 is a section on the line 2--2 of Fig. 1.

Fig. 3 is a side elevational view of one section extended with the two portions in the same plane. j f

Fig. 4 is a top plan view of the invention.

The improved mold comprises a device polygonal in plan and it may be either in the form of a pentagon, heXagonJ heptagon or Octagon depending on the size stack to be molded. Each section comprises the upper and lower members 1 and 2 which in elevation are of the shape of an isosceles trapezoid. The two members are hingedly connected together at the larger bases of the trapezoid by means of hinges 3.

Both members of each section are identical in construction and diEer only in their disposition in the mold 'as a whole, the one member being the reverse of the other. Both are formed with the longitudinal rails 4 and 5 which are connected together by the slats 6 and 7, the latter slats being the outside slats of the member and the slats 6 the intermediate slats. This arrangement leaves vSpecification of Letters Patent.

the spaces between adjacent slats wider in the vicinity of the rail 4 than in the vicinity of the rail v5. In the formation of several sections into the mold, the rails 5 of the sections 2 become the bottom rails of the mold while the rails 4 of the said section as well as the rails 4 of the section 1 become the intermediate rails of the mold. These latter rails .being of greater length than the former rails, the mold is of necessity of greater diameter at the center than either at the kbottom or the top, the top being of the same diameter as the bottom.

On both the rails 5 and 4 of the member 2 at one end there are attached the hingedly mounted hasps 8, while at the other ends of these two rails there are attached the staples 9. Thus any member 2 is connected with the adjacent member 2 of a succeeding section by having its hasps 8 engage the staples 9 of the said adjacent member 2 and these hasps are retained in engagement with the staples by means of snap hooks 10 which are secured by means of chains 11 to the rails in the vicinity of the staples.

The members 1 of the several sections are equipped with but one staple and hasp apiece and both the staple and hasp are attached on the top rail 5.

In the assembling of the several sections to form the mold, all of the slats 6 and 7 stand on the inside of the assembled structure, the rails 5 and 4 'being on the outside. In building up a stack of hay or grain, only the lower members 2 are interconnected by means of the hasps and staples, the top members 1 being allowed to swing down on their hinges 3, Vhen the mold is filled up to the height of the members 2, the members 1 are then raised and interconnected at their upper edges by attaching the staples to the hasps and connecting the snap hooks. Thereafter the filling of the mold is completed by throwing the hay or lgra-in over thelOO a loss of space which might be filled With n one of the sections 2, Which section is illustrated in Fig 3, there are intermediate rails 12 secured to the slats 6 and 7 of both the members 1 and 2. These rails l2 together With the rails 4 provide a ladder upon which a person might climb to the top of the mold to perform any operation Within the mold that it is desired to perform from the top.

It is obvious that the device may be used for stock feeding purposes, in Which case allthe upper members l would be left interconnected and alternate members 2 released and raised, thus providing a Way in Which stock might feed from the lower side of the structure, the mold the `While retaining the stacked hay in compact Condition.

The invention having been described what is claimed as new and useful is:

A device of the character described comprising a plurality of sections each composed of two members hingedly connected together, means for detaehably connecting together all of the said sections, the bottom members of the sections interconnecting as Well as the top members, the said sections being formed in the shape of an isosceles trapezoid with top and bottom horizontally disposed rails and slats interconnecting the two rails, the slats being uniformly spaced along the two rails, whereby there is provided a mold of greater diameter at an intermediate point in its height than its diame- Jrer at its bottom or at its top, the slats being onthe interior of the mold and disposed in a substantially vertical position, so that hay and the like may `be thrown into the mold down into which it will settle Without the formation of pockets.

In testimony whereof I aiiix my signature.
